At Which Stage During the Translocation of a Protein Destined

At which stage during the translocation of a protein destined to become an integral membrane protein is its polarity (for example, N-terminus cytoplasmic; C-terminus extracellular) determined?

A) during translation, by the polarity of association with signal recognition particle.
B) during translocation into the endoplasmic reticulum.
C) during translocation into the cis?Golgi.
D) during translocation into the trans?Golgi.
